Circle the common factors of 18W and 30WZ

Mathematics
1 answer:
Alex2 years ago
6 0

Answer:

6, 6w, 3w, z and w.

Step-by-step explanation:

The common factors are those values that can divide 18w and 30wz perfectly.

Take a look at 6, 6 can divide both perfectly to give 3w and 5wz respectively.

We move on to 6w, this can also work perfectly to yield 3 and 5z.

6xz is not a factor as both values do not contain any x term.

3z is not a factor. Although 30wz has a z term, 18w does not.

3w is a factor as it can give 10z and 6 when used to divide the terms.

Z is not a factor as the 18w term does not contain a z term.

10w is not a term as it can not divide 18w perfectly

w is a term as it can divide both 18w and 30wz perfectly to yield 18 and 30z respectively.

Alborosie

Answer:

80.67 hours

Step-by-step explanation:

Data provided in the question:

The number of weekly hours worked :

78 85 82 79 77 82 81 82 81 81 82 78

total number of observations = 12

Now,

Mean = (Sum of all the data values) ÷ (Total number of data values)

or

Mean = ( 78 + 85 + 82 + 79 + 77 + 82 + 81 + 82 + 81 + 81 + 82 + 78 ) ÷ 12

or

Mean = 968 ÷ 12

or Mean = 80.67 hours

How many ways are there to put 8 beads of different colors on the vertices of a cube, if rotations of the cube (but not reflecti
Delvig [45]
What is being requested, if I'm not mistaken, is the number of permutations for placing each of the 8 beads on the vertices of the cubes;
In this case, we have 8 different beads and 8 possible locations for each of them;
So the number of permutations is:
8! = 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 40320

A campus radio station surveyed 500 students to determine the types of music they like. the survey revealed that 199 like rock,
Ostrovityanka [42]
<span>There are 24 who like both rock and country. There are 8 who like all 3 types, and these eight have been counted under the 24. This means that the number who like rock and country but not jazz is 24 - 8 = 16.
We are given a total of 155 who like country. We subtract the 16 who like both rock and country, and are left with 139 people who like country but not rock. (It does not matter whether they like jazz or not).
The probability is 155 out of the total of 500, so 155/500 = 31/100 = 0.31.

Mario has a business selling muffins. Let x be the price of a muffin. Then, the profit P for Mario’s business is given by p(x)=-
Rufina [12.5K]
To make a positive profit p(x)>0 we need to make:
-100 x^{2} +350x-150 \ \textgreater \  0

Now we solve this for x:
-2 x^{2} +7x-3 \ \textgreater \ 0

We have:
a = -2
b = 7
c = -3

We will use formula for quadratic equation:
x_{1} =  \frac{-b+ \sqrt{ b^{2}-4ac } }{2a}  \\  \\  x_{2} =  \frac{-b- \sqrt{ b^{2}-4ac } }{2a}  \\  \\  x_{1} =  \frac{-7+ \sqrt{ 49-24 } }{-4} = \frac{-7+5 }{-4} = \frac{-2 }{-4} = \frac{1}{2}  \\  \\  x_{2} =  \frac{-7- \sqrt{ 49-24 } }{-4}  = \frac{-7-5 }{-4} = \frac{-12 }{-4} = 3

We got two solutions. One is fraction other is whole number. We will not consider fraction because the amount of muffins sold must be whole number. So our solution is:
x>3
